Product Description

PureLine Crystal Pure Salt Chlorine Generator PL7701

Crystal Pure Salt System by PureLine

The PureLine Crystal Pure Salt System makes the process of chlorinating the pool a breeze for you. When your pump runs, you will be producing chlorine, ensuring a steady dose into your pool water. The more consistent your chlorine levels are in your pool, the fewer chemicals you will use overall. Free yourself and your pool guests from the itchy, dry feeling of regular chlorine. With a salt water chlorine generator, the water feels smooth and won't leave a white residue on your skin. The Crystal Pure generator cell easily plumbs in-line and has quick disconnect unions for easy access. 

Features:

  • Durable design
  • Max. Chlorine Production Per Day = 1.06 Lbs.
  • Economical to use
  • Simple operation & maintenance
  • Large chlorine capacity
  • Low energy consumption
  • 1 Year warranty
  • Digital display and LED indicators
  • Self-cleaning
  • Adjustable chlorine output
  • Super chlorination mode
  • Water flow detector
  • Low salt and overload indicators
  • High & low temperature protection (working temperature from 50F to140F)

Crystal Pure Optional Add-On Accessory Package

The Crystal Pure Optional Add-On Accessory Package includes several convenient tools for your swimming pool salt system. The package includes a Salt Cell Cleaning Stand, Salt Test Strips, and a Dummy Cell. The Cleaning Stand simplifies cell cleaning and eliminates having to soak the cell in a bucket of muriatic acid solution. Salt Test Strips are used to accurately measure the salt level in your pool. The dummy cell is used during cell cleaning, winter, and spring startup.

Optional Add-On Accessories

Salt Cell Cleaning Stand

This cleaning stand simplifies cell cleaning and eliminates having to soak the cell in a bucket of muriatic acid solution. This Cleaning stand is used for PureLine Crystal Pure salt cells. You should clean your salt cell every 2 months to avoid calcium build up on your salt cell. By cleaning your salt cell regularly you will prolong the life of the cell. Also if you get too much calcium build up on the salt cell then the system will stop producing chlorine, regular cleanings ensure that your salt system will not stop producing chlorine.

Order Your Salt Cell Cleaning Stand

Salt Test Strips

Salt Test Strips are used to accurately measure the salt level in your pool. The Crystal Pure Salt System does measure and give salt readout levels on the power supply however it is nice to have salt test strips upon startup of your Salt System. During startup up you will use your test strips to make sure that you add the correct amount of salt to your pool, it is also good to be able to compare the salt readings on the power supply to those of the salt test strips to make sure the system is giving accurate salt readings. 

Straight Pipe Place Holder - Dummy Cell

This straight pipe holder also called a dummy cell is used for several scenarios which we have listed below.

Winter: It is suggested that in areas of the country that you close your pool for the winter that you replace your normal cell with this dummy cell, the reason being is that the standard cell is expensive and by removing the standard cell you will prolong the cell's life.

Cell Cleaning: When you remove your normal cell for cleaning it is nice to have the dummy cell as you can replace the normal cell with the dummy cell so you continue to filter your pool while you clean your cell.

Spring Start-Up: The dummy cell is great to use during spring start up as quite often the pool can be quite dirty and you don't want large dirt and debris to get lodged in your standard salt cell.

The LT model comes with a 1-year warranty and the standard model of this 20k series comes with a 2 years warranty.

?     Asked on 6/8/2019 by Joe

Hello, I have a kidney shaped pool with approximately 14-15,000 gallon as best as I can calculate. I been purchasing the 40,000 gallon salt generator for many years and my thought/question is: Have I been over buying for my pool all of these years? Going forward, should I simply purchase the 20,000 gallon salt generator and save myself some money? These units are very expensive and do not last very long even when well-maintained. Your feedback is much appreciated. Thank you in advance!
 Reply

A  Answered on 6/8/2019 by InyoPools Product Specialist Patrick P.

Hi Joe, We always suggest going with the largest system and largest warranty your pocketbook can afford. Here is our reasoning... 1.) The cells are rated on hours of use a larger cell will have more blades meaning it can produce more chlorine, in return you can run your cell at a lower % output which means the cell will run for few hours and you will get a much longer life out of the cell. With the larger cell if you get into an algae situation you can crank up the production to 100% to produce some serious amounts of chlorine. 2.) A cell also goes bad when the Rithinum coating wears off of the titanium cell blades and the higher warranty systems have more Rithinum coating on the blades thus making the cell last longer. So to answer your question I would stay with a 40K system.

?     Asked on 6/2/2019 by Allen

Hello, I am waiting for some parts that were missing on my order but I was wondering. Does the cell gets mounted in a specific direction or just the flow switch?
 Reply

A  Answered on 6/3/2019 by PureLine

Hi Allen, Just the direct of the flow switch is what matters there is an arrow on the flow switch and you will want the water flow to flow in that direction. The direction of the cell doesn’t matter.

?     Asked on 5/29/2019 by allen

Hello, I am buying the VS pump PL1615 and the salt generator PL7708 today and I have a final question. Currently I have a timer with my single speed 240V pump. How will I wire the salt generator? Will the control box automatically start if I use the timer? Can I connect the pump and the salt generator thru the timer? No sure if you understand my question. Please let me know
 Reply

A  Answered on 5/29/2019 by InyoPools Product Specialist Patrick P.

Hi Allen, I have a similar set up on my pool and I don't have the salt system set up on a timer, I just have the pump use its timer, the salt system will only produce chlorine if water is passing through the flow switch. For example if you have your pump set to run for 8 hours and you have the salt system set at 50% then the salt system will produce chlorine 30 minutes out each hour that the pump is turned on, so in this case 4 hours total. So the salt system controller will have power all the time and it will produce chlorine based on the flow switch.

How do do I go from DE filter to salt ?
 Reply

A  Answered on 5/20/2019 by InyoPools Product Specialist Patrick P.

Nothing special needs to be done in regards to your D.E filter. Your D.E filter would stay in place as that is the device which filters the debris out of the water. The salt system is a device which manufacturers chlorine to sanitize the pool. The D.E. filter and salt system serve two separate functions.

We have a 10,000 gallon inground and would like to switch to salt water. I have purchased all my new motors from you and have been satisfied so far. Was wondering what I need to switch. Our pump is a Hayward pro series sand filter approved for fresh or salt water . S210T
 Reply

A  Answered on 5/17/2019 by InyoPools Product Specialist Patrick P.

Hi Amber, This PL7708 PureLine Crystal Pure Salt System would really be the main item you need. You will require salt which you can purchase at your local hardware store, for a 10,000-gallon pool you will need about 8 bags at approximately $8 per bag. For startup it would be helpful to have some Salt Test Strips We also carry this Salt System Accessory Kit which includes a stand for cleaning your salt cell, salt test strips and a winter dummy cell. You can read about the purpose of each of these accessories through this link Salt System Accessory Kit. These accessories are not mandatory just optional add on accessories which might come in handy.

?     Asked on 4/26/2019 by Sue

I am considering the PL7708, I have 1 1/2" piping and limited space on the return line. Will this work with my pipe size and can the cell be mounted vertically? My pool is 18,200 gallons this model should be ample correct?
 Reply

A  Answered on 4/27/2019 by InyoPools Product Specialist Patrick P.

Hi Sue, Yes this cell can be used with 1.5" pipe and the system includes these adapters, also the cell can be mounted vertically. Yes, this system will work on an 18,000-gallon pool. If your pocketbook can afford it then we always suggest oversizing to the 40,000 gallon Crystal Pure Salt System as you will get longer life out of your salt cell and the larger cell will really allow you to crank up the chlorine production if you ever get into a demanding situation like an algae bloom. With this being said the 20,000-gallon system still would be sufficient.

Is this the only thing I need to convert my chorine pool to a salt water pool. What will I save in chemicals and how often do I need to had in chemicals, especially if I am gone for two months.
 Reply

A  Answered on 4/15/2019 by InyoPools Product Specialist Patrick P.

Hi, Yes this is all you will need to convert your pool to salt minus the salt itself. The PL7708 will be creating all of your chlorine needs so whatever you were spending in Chlorine will be your chemical savings as you will no longer need to purchase chlorine tablets, liquid chlorine or shock. You will need to keep your pH and CYA within proper levels, the pH is normally adjusted every few weeks with muriatic acid and your CYA is adjusted every few months with Stabilizer.

I'm looking to replace my Pentair IC 20 system will the cell from these units screw in using the same unions or will some plumbing work need to be done?
 Reply

A  Answered on 3/25/2019 by InyoPools Product Specialist Lennox H.

Hi Scott, This cell does come with various unions and it will accommodate the Pentair unions however the cell length is different so there will be some minor re-plumbing. We do have the PureLine Crystal Pure Max Salt Chlorinator which has the exact same cell dimensions as the Pentair Intellichlor which would mean no re-plumbing if you go with the PureLine Crystal Pure Max Salt Chlorinator.

        Thank you. I currently have the Pentair IC20. I think I'll be replacing it with the Pureline 40,000 gallon unit ONce I verify that the cell for my Pentair needs to be replaced. It looks like for the cost of just the Pentair cell, I can replace the entire unit with a larger Pureline.

My above ground 15X30 Ester Williams pool is12000 gal., with a Hayward chlorinator, pump and DE filter. My skimmer goes directly to the pump and filter, filter goes to the chlorinator and to the pool inlet. Where do the parts for the salt water system get placed? How is the Salt added? Do I keep the chlorinator? How much salt do I need to start up a salt system and how much for a season? (Late May to early Sept). Can you include a diagram in your response? Thanks, John

Hi, John. The Controller is mounted on the wall, the cell and flow switch will be installed after the filter. The salt is added directly to the pool's water. This system will eliminate your chlorinator. Check out our How To Install a Crystal Pure Salt Chlorine Generator guide.

What is the output in grams per hour of each model? Should you have any consideration on the max gallon capacity of each model according to climate (tropical weather)?
 Reply

A  Answered on 11/16/2018 by PureLine

Hi Julio, The 20,000 Gallon systems will output 1.06 lbs. (480 grams) of chlorine per day, The 40,000 Gallon systems will output 2.1 lbs. (952 grams) of chlorine per day and The 60,000 Gallon systems will output 3.18 lbs. (1,442 grams) of chlorine per day. For more tropical climates we would suggest upgrading to a larger model as this will give you the extra chlorine production if you ever need it.
